Question

The correct order of increasing bond angle in following *

(a) CH₄<H₂O<CO₂<BF₃

(b) H₂O<CH₄<BF₃<CO₂

(c) H₂O<BF₃<CH₄<CO₂

(d) BF₃<CH₄<CO₂<H₂O

​

Answer 1

Answer:

(b) is correct option

Explanation:

CO2 sp-hybridised ,bond angle is 180°

BF3 -sp2 hybridisation bond angle is 120°

NH3 - sp3hybridised (1 lp)

so,less repulsion . bond angle decreases to 107°

H2O - sp3hybridised (2 lp) so more repulsion and bond angle decreases to 105°
